So, you know how some folks are complaining that their iPhone 4 has a signal degradation issue when touching the antenna in a certain spot? Well, one simple way to solve it is to use an iPhone case, so that you aren’t directly touching the stainless steel band on the outer perimeter of the iPhone 4. The thing is, the Apple iPhone 4 Bumper case is $29, which is ridiculously overpriced. However, the fine folks over at cases.com are offering up a free iPhone 4 silicone LifeGrip case to anyone who asks. You do have to pay for shiping, but in the end, you are paying $3.73 total for a case that will get rid of any antenna-related reception issues, and protect your iPhone from drops as well. Can’t really complain about any of that, now can you?
